Abstract: To lower coal consumption of air-cooled units, the idea and technical points of hybrid cooling are introduced. By adopting auxiliary cooling equipment, the radiating area of the air-cooling island is increased to solve the problems of poor unit economics and load limitation due to high back pressure in summer; while in high back-pressure operation in winter, exhaust steam heating can be realized so that the efficiency of cogeneration is improved. Optimization on energy saving with multiple technologies accommodating local conditions and local resources is suggested. In addition, taking the wet peak cooler, the evaporative cooler and the heat pump for example, detailed implementation schemes on comprehensive application of hybrid cooling are presented.
